PROBLEM TO BE SOLVED: To prevent the higher harmonic noise of the clock frequency of control signals for generating a gradient magnetic field from being superimposed on the reception band of MR signals. SOLUTION: The clock frequency of the respective control signals Sa and Sb for controlling the generation of the gradient magnetic field and a high frequency magnetic field is set higher than the frequency band of the reception band Rb of the MR signals m, is set to 500 kHz higher than 400 kHz of the reception band Rb of the MR signals m for instance.
